Greetings from germany and a question about high idling my V70R

[Hamburger]

Short Update, DO88 Intercooler works really good, 3-4° Difference IAT vs Outisde temp, thats good.
My High Idling Problem is still present, maybe i'll stumble upon another error or i'll leave it as it is, no more searching for that.

I have an issue with Engine check lights on 2 friends cars that also irritate me more than them. I have limited access to the cars for long enough to do further work on them. So they just live with the issue as cars seem to drive fine.

I've improved performance of my old stock intercooler a lot by rinsing it with solvent. It worked great, until it got soaked in oil again
